The Beiteynuese Republic was the successor state to the Kingdom of Yishelem. It was founded in 2863 after various acts passed in the (former) kingdom's legislature by the republican parties of the nation. Because the Holy Luthori Empire considered the creation of the Republic an illegal act based on the Treaty of Yishelem, it declared war on the new nation the same year of its formation. The Beiteynuese Republic lost the Beiteynu-Luthori War, and, after the Beiteynu-Luthori Peace Conference was over and the Treaty of Poesy was signed by both nations, the country ceased to exist in 2887, and was succeeded by the Commonwealth of Yishelem and Beiteynu.
